Features

• Add json resource in global registry. The json resource is now registered by default, it's not necessary anymore to explicitly register it
• Add argument passing to Resource instances from a ResourceSet. This feature allows the user to pass arguments to a resource when using get_resources or create_resources from a ResourceSet.

Bugfixes

• Fix issue with file protocol starting with file:/.
• Fix deserialization of boolean in json resources.
• Fix enum literals serialization in json resources. Depending on the "level" where's defined the EnumerationLiteral, the serialization should be different: (1) if serialization happens at the metamodel level, all the internal information of the EnumerationLiteral should be written in the json file, (2) if serialization happens at the model level (a model uses a literal defined in the metamodel it conforms to), the EnumerationLiteral should be serialized only by its name.

Miscellaneous

• Pass from "beta" to "stable".
• Add pypy 3.9 and 3.10 as target test Python VM.
• Fix CHANGELOG.rst.
